In an image scanning device, an Automatic Document Feeder (ADF) frame accommodating an ADF is provided openable and closable on an upper surface of a device main body via a hinge member. In the hinge member, a frame supporting part fixed on one end part of the ADF frame and a base part fixed on the device main body are mounted in a manner capable of being swung. A rear side edge of the ADF frame is supported by the frame supporting part of the hinge member. The ADF frame is provided openable and closable so as to expose a bottom surface of the ADF frame to a front side.

A paper transportation device includes a paper guide body, which forms an inner guide surface of a transportation path, side frames on which a shaft of a transportation member disposed in the transportation path for transporting an original document is mounted and a gear shaft of a drive transmitting gear, which is provided in a standing condition on the side frames and transmits rotation of a drive source to the shaft of the transportation member. The paper guide body, the side frames and the gear shaft are formed integrally by resin.

Data processing machine

A paper feeder includes a sheet supply unit that feeds sheets placed on a sheet placing part, a separating roller the separates the sheets fed by the sheet supply unit one sheet at a time and supplies each sheet to a sheet transportation path, a transportation roller that transports the sheets provided downstream of the separating roller and a link mechanism connected to the transportation roller via a transmitting unit. When the transportation roller rotates in a sheet transporting direction, the link mechanism swings so that a shutter opens the sheet transportation path and maintains an opened state. When the transportation roller rotates in a direction opposite to the sheet transporting direction, the link mechanism swings so that the shutter closes the sheet transportation path.

An image forming apparatus includes a lower shell that defines an outer contour of the apparatus. A feed roller shaft holding member, a separation roller shaft holding member, a press roller shaft holding member, a platen roller affixing unit, a discharge roller holding member and a pickup roller shaft holding member are all formed integrally with a platform of the lower shell. Left and right frames of the apparatus holds a paper cassette. The left and right frames and the platform are formed integrally with the lower shell.
